Description
For quite sometime i have this occuring at least once or 2 per month. Can't seem to see what trigger it.
Restarting my router don't change a thing neither is reasking a new DHCP communication from networking pref panel, only a computer reboot fix this.
Linked is a syslog of a typical occurance.
I got this on more than one computer but it seem to be driver related as on some i never see the problem.

DAEMON 'DHCP': /dev/net/rtl81xx/0: Timeout shift: 4294249842 msecs (try 6)
#15723 shows similar lines though they have 3 or 4-digit timeout shift values, whereas in this one the "4294249842" value is huge (it's 0xfff50d72 in hex)

Cisco docs say that NACK's are most likely to happen if there is more than one DHCP server on the network. Easiest way to check that is probably with wireshark. Our DHCP client could also keep track of what IP is responding, and warn if there is a change in IP.
I need to look at code a bit to refresh mem, but that number looks weird.

I have similar problem with this driver (rtl81xx) and it happens when I cold boot into Haiku. Restarting my PC doesn't help, but when I boot Windows, it connects without problem and then when I reboot to Haiku, Haiku is working well too, so I have a feeling that Windows driver sets some state that Haiku driver does not.
The difference for me is that I don't have this overflow values for DHCP timeouts.
My setup:
- hrev54982 x86_64
- Realtek® 8111H Gigabit LAN Controller - this is on MSI X570-A Pro motherboard
There are other tickets that might be caused by the same problem: #15866, #16731.

I note that Realtek has their own FreeBSD driver for this class of hardware, separate from FreeBSD's upstream version. I think when I looked at it once, the internals looked very different from FreeBSD's.
The one thing I see in the posted syslog that stands out:
KERN: [net/rtl81xx/0] watchdog timeout
Please always mention haiku revision.
